SPECIFICATION forming part of Letters Patent No. 337,265, dated March 2,1886,

Application filed December 16, 1885. Serial No.185,859. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM M. HELMs, a citizen of the United States,residing at Steubenville, in the county of Jefferson and State of Ohio,have invented a new and useful Machine for Upsetting or Shrinking Wagon-Tires and for other Purposes, of which the following is a specification.

My invention relates to improvements in wagon-tire reducers in which theheated iron is held while the shrinkage is being effected bymanipulating with a hammer.

The objects of my invention are, first, to provide a machine that can beoperated upon an anvil; second, that will be adapted to other uses thansimply tire-shrinking; and, third, that will be simple in construction,thus male ing a convenient, useful, and cheap machine, all of whichobjectsI attain by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a perspective view of the machine upon ananvil, A, showing a section of a tire, c, in position ready to bemanipulated with a hammer in the hand of the operator. Fig. 2 shows themachine in an upright and open position disconnected from the anvil A,and also the manner in which the connection is made therewith.

Similar letters refer to similar parts throughout both views.

The anvil A, upon its block, as shown in Fig. 1, constitutes thefoundation of the machine, the swage-hole a, Fig. 2, shown also bydotted lines in Fig. 1, forming a socket for the reception of themandrel b ofthe bedblock S, in which it is held firm and solid while theoperation of reducing the tire or other manipulation of hot iron isbeing performed. The bed-block S is slightly dished or concaved on itsface, to preserve the circular formation of the tire while it is beingupset or reduced, and has file-teeth t 15 near to the ends,for holdingthe'iron while it is being manipulated. On the back side of the bedblockS, at each end, are lugs d d for connecting the levers e e to thebed-block S, which is done by passing a-pin, f, through bosses g on thelevers e 6. On levers e e are worked or formed jaws h h, in suchposition on the levers that when they are brought down the jaws are,brought in exact contact with the teeth it on the bed-block S, so as togrip and hold the hot iron when placed between them, as shown in Fig. 1.The levers e e are made in open form, and are held apart, where theyconnect with the lugs cl d of the bed-block S, by a tube or sleeve, 0,which forms shoulders for the bearing of the levers-to prevent themdrawing together when the pressure is brought upon them, and throughwhich the connecting-pin f passes, as shown in the broken section, Fig.2. The lever I is curved downward, just where the connection is madewith the levers e 6, with a hook, h, formed on the end, as shown in Fig.2, for the purpose of catching under the heel of the anvil, as shown inFig. 1, when brought into requisition for holding the iron. The boltj,passing through and connecting the levers e 6, one on either side ofthe lever I, forms a fulcrum for lever I and connects the levers e e andI, so as to form a continuous lever from the connectingpin f to thefarthest end of lever I. The connected levers e e and I, as described,constitute a duplex or double-acting powerful lever. The connecting-boltj,passing through the outermost extreme ends of levers e 6, constitutesthe fulcrum of the lever I, while the lift of the lever I is under theheel of the anvil, as shown in Fig. 1, so that when a pressure is placedupon the outermost end or handle of lever I, with the hook 7c caughtunder the heel of the anvil, as shown in Fig. 1, a powerful pressure isproduced upon the jaws h h of the levers e e, as shown in Fig. I.

How to use the machine.To use the machine for shrinking tire, the tireis first properly heated and a portion of it bent inwardly,son1ewhat inthe shape of an inverted letter U, as shown in Fig. 1, when it is placedin the machine with the U shaped part between the levers e e projectingupward. The lever I is then brought down, with the hook k caught underthe heel of the anvil A, as shown in Fig. 1, clamping the tire betweenthe jaws h h and the bed-block S, and holding it firmly while the Ushaped part is being brought down to the plane of the bed-block by theuse of the In combination with an anvil, the seat-block IO hammer in thehand of the operator, thus S, levers e e and I, constructed as shown andshrinking the tire to the size desired. Iron described, and the lever I,hooking under the may be thus held in this machine while it is edge ofthe anvil, for the purpose set forth.
